Today i tried the AC in my car for the first time since i bought it in March, i never really felt the need to use it up until today. It worked fine as long as i was moving, but as soon as i stopped or pressed the clutch the engine revved down to 500rpm and cut out.
It might be worth mentioning that a couple of weeks ago the engine would rev very low and cut out when i tried to start it - it would take a couple of attempts before it got going.
Also, this past week the idling revs have been erratic, one day it would be 750 or there abouts and the next day 1000.
I've done a bit of research and found that the throttle body would be a good place to start. So i've decided to clean it but have no idea what solution to use or where to get it from.
Is there anything else that could cause this problem?
